Rick,
Knickers aren't in a knot. Now that the educational lesson is over, do you have any insight to the question? Which is;
Can you help me understand why Ford would have designed this air cleaner set-up this way. I guess one reason could be because it was the original design for the 861D (i.e. 1957-1958) and Ford changed the design in later year models or perhaps the different set-ups were specific to a particular farming application.
Your input specific to the question would be appreciated.
Thanks. Tom
